Hi

I have a problem loading XML-documents that contain the xsi:nil-attribute in the following situation:

 - XML-sample 'Simple.xml':
    <?xml version="1.0" encoding="UTF-8" ?>
   <Simple xmlns="http://www.simple.be/Simple"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <MyDate xsi:nil="true" />
   </Simple>

 - XML-sample 'Simple2.xml':
    <?xml version="1.0" encoding="UTF-8" ?>
   <Simple xmlns="http://www.simple.be/Simple"
           xmlns:dummy="http://www.dummy.be/dummy">
      <MyDate dummy:nil="true" />
   </Simple>>

 - (simplified) C++-code used to load the XML-document
   MSXML2::IXMLDOMDocument2Ptr DOMPtr = NULL;
   try
   {
      if (DOMPtr.CreateInstance (__uuidof (MSXML2::DOMDocument40)) !
          = VARIANT_TRUE)
      {
         DOMPtr->async = VARIANT_FALSE;
         DOMPtr->validateOnParse = VARIANT_FALSE;

         if (DOMPtr->load ("Simple.xml") != VARIANT_TRUE)
         {
            ...
         }
      }
   }
   catch (_com_error e)
   {
      ...
   }

The load fails when validateOnParse = VARIANT_FALSE with error 'xsi:nil attribute on element 'MyDate' is invalid' (code: -1072897995) and I have no clue why.
The MSXML-help for validateOnParse states the following:
'Boolean. The property is read/write. If True, it validates during parsing. If False, it parses only for well-formed XML. The default is True.'
If you set this property to 'True':
 - What exactly is validated?
 - What is it validated against?

And... why is there no problem when loading 'Simple2.xml'?



Kind regards
